Metals and Mining - KWS Manufacturing

Mining, Metals, & Minerals Processing Equipment

The mining, crushing, washing and drying of many metals and minerals is accomplished by the use of conveyors. Copper, Iron ore, taconite and uranium are metals that are conveyed using KWS Screw Conveyors and Belt Conveyors. Coal, limestone, sand, kaolin clay, potash and soda ash are minerals that we have conveyed from the mines to the crushers and other areas of the process. Our conveyors are extremely heavy duty to withstand the harsh conditions. We use abrasion-resistant materials to build our conveyors because we know that downtime is not an option.
